Toyota Tundra tonneau cover fitment depends on more than the model year. Older-generation Tundras were offered with different bed lengths, and some have Toyota's factory Deck Rail System inside the bed. TruXedo assigns separate Lo Pro roll-up cover part numbers for those configurations. Use this reference to identify five 2007–2021 Tundra applications without relying on a generic “fits Tundra” product title.

What matters: bed length and Toyota's Deck Rail System

6-foot-7-inch bed: 545701 versus 545801These two Lo Pro covers describe the same nominal bed length. The difference is the factory cargo-management track: 545701 is listed without the Deck Rail System, while 545801 is the version for a truck equipped with that system.
8-foot-2-inch bed: 546701The 546701 is intended for the longer Tundra bed without the Deck Rail System. It is not a replacement for a 6-foot-7-inch cover. There is a separate manufacturer part for certain long-bed trucks with factory tracks, so confirm your exact bed equipment before purchasing.

Short-bed Tundra models: TruXedo also identifies 563701 for the 5-foot-6-inch bed without factory Deck Rail tracks, and 563801 for the 5-foot-6-inch bed with tracks. The 563801 application is listed for vehicles with or without Trail Special Edition bed storage boxes. These are separate cover kits from the 6-foot-7-inch and long-bed versions.

563701 2007–2021 5 ft 6 in Without factory Deck Rail System
563801 2007–2021 5 ft 6 in With factory Deck Rail System

All five are black, soft roll-up TruXedo Lo Pro covers intended for manufacturer-listed 2007–2021 Toyota Tundra trucks. The stated bed lengths are application designations, not the box dimensions or a universal measurement between arbitrary points on the truck.

Deck Rail System is a fitment distinction, not an accessory preference. Inspect your Tundra's factory bed-side cargo tracks before choosing between 545701 and 545801. Both may appear under the same year range and bed size in a general catalog.

How to identify the correct replacement

  1. Start with the full truck year and body. These five numbers refer to the 2007–2021 Tundra generation; do not assume a 2022-and-newer truck uses the same system.
  2. Confirm the nominal bed length. Distinguish the 5-foot-6-inch, 6-foot-7-inch and 8-foot-2-inch beds. If measuring, follow the vehicle or cover manufacturer's published bed-length method.
  3. Look for the Toyota Deck Rail System. Check the inside bed rails for factory-installed cargo tracks and their hardware. A truck with tracks can require different tonneau clamps or rail mounting parts.
  4. Check special bed equipment. Factory storage boxes, utility racks or other bed-mounted accessories can change compatibility. The 563801 listing is specifically identified for 5-foot-6-inch Tundra beds with the Deck Rail System, with or without Trail Special Edition storage boxes. Do not extend that approval to the other MPNs without checking their individual application listings.
  5. Compare the original cover number. If replacing a worn cover, look for the complete manufacturer part number on paperwork, hardware or packaging. Do not assume fabric, bows, clamps or rails from a different Lo Pro kit interchange.
  6. Check the whole installation. Lo Pro uses inside-bed-rail mounting, a roll-up vinyl panel, hook-and-loop sides and a trigger latch. Confirm clamp location, tailgate operation and any other cargo accessory clearance.

Replacing only part of an existing cover?

If the fabric is damaged but the side rails remain, identifying the complete cover part number is still important. Replacement fabric, support bows, latch parts and mounting clamps need the correct TruXedo series and application. A matching 6-foot-7-inch bed does not establish that the rail hardware on 545701 and 545801 is identical.
